Recent developments in power electronic device technology promises faster
switching capability at high power. The hybrid pulse width modulation method
which requires two of the four switches in a full bridge inverter are used, and
enable pulse pattern operation at high frequency. The use of two level
switching instead of three level switching enables the use of higher frequency
for given computation time delay. The proposed control scheme is implemented
using bi-polar junction transistors (BJT) controlling an inverter to produce a
very low frequency (THD) sinusoidal output voltage. Simulation and
experimental results are presented to verify the performance.
